OLIVER PALMER, or CINCINNATI, o Io.

Letters Patent No'. 101,656, dated April 5, 1870.

IMPBOV EMENT IN TRACE-FASTENING-S.

Z'he Schedule referred to in these Le tters Patent and making part of the same.

I, OLIVER PALMER, of Cincinnati, Hamilton county. Ohio, have invented a new and useful Trace-Fastening, of which the following is a specification.

Nature (ma Objects of the Invention.

My invention relates to a fastening for connecting ihe tngs or traces of draft-animals with the whittletree or sin gle-tree, which combines great security with facility of hitching and unhitching.

General Description withReference to the Drawings.

Figure 1 is a perspective view. of a portion ot'a whifllletree or single-tree whereon my improved fasteningis shown in its open condition. V

Figure 2 is a partially sectionized side elevation of the same in its closed condition.

Figure 3 is a. side elevation of the device in its most open condition. 1

Figure 4 is a partially sectionized side elevation showing a modification of my device.

A represents a portion of a whiflletree orVsingle-tree with its cock-eye B.

Screwed fast or otherwise secured to the upper side of the tree is a spring, 0, to which is hinged an arm, D, whose end is bent downward so as to form what I call the guard E, which guard, when the device is fast ened, occupies the cock-eye along with the catch F, (projecting from the same arm,) whose end f is sharpened or chamfered so as to readily enter the cock-eye, and is provided with a shoulder, f, which, engaging under the cock-eye, prevents the accidental. escape of the catch and guard thereirom.

The guard E discharges the functions of the ordinary leather thong in confining the trace, and also protects the catch F from the chafing of the traces.

For additional security the shoulder f is, in the preferred form of my invention, notched or indented,

f", as shown in figs. l, 2, and 3, to engage behind a vcorresponding shoulder, 11, on the under side of the cock-eye, so as to requiretwo movements or'rnanipulations to disengagethe catch, namely, first a depression to liberate the indentation, and then a pressure inward to liberate the shoulder from the cock-eye- The preferred form of my improvement has also a tongue, G, which, projecting rigidly from the under side of the spring 0, outward underneath the arm D, presses upward against said arm with sufiicient force to cause the liberated catch-to spring back out of the way, as ea :n in fig. 3.

The tension of the spring 0 may be regulated by a set-screw, H.

An inferior modification of my invention is seen at fig. 4, where a plain shoulder replaces the indented one. The fastening, when in this form, may be liberated by a simpleinward pressure of the catch.

Claims.

I claim herein as new and of my invention- 1. The spring 0, hinged arm D, and shouldered catch F, combined and adapted to operate as set forth.

2. In this connection, the indentation f" adapted to engage behind the shoulder b on-the under side of the cock-eye, as and for thepurpose designated.

- 3. In the described combination with the elements B, C, D, and F, the guard E. V

4. In the described combination with the elements 13, O, D, and F,t-he tongue G.

In testimony of which invention I hereunto set my hand.

OLIVER PALMER.
